Adaptable and locking bracket assemblies for a load stop and load lock pallet rack system

ABSTRACT

The invention depicted herein is a simple connection bracket used in conjunction with standard vertical and horizontal pallet rack beams and locking mechanisms to prevent material handlers from damaging walls during placement of pallets or from removing pallets from storage on or under pallet racks.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application references U.S. patent application Ser. No. 13/675,346 filed on 13 Nov. 2012, entitled “ADAPTABLE BRACKET ASSEMBLY FOR PALLET RACK LOAD STOP SYSTEM,” and references and claims the benefit of U.S. Provisional Patent Application No. 61/729,409 filed on 22 Nov. 2012, entitled “ADAPTABLE LOCKING BRACKET ASSEMBLY FOR A LOAD LOCK PALLET RACK SYSTEM,” the disclosure of which is hereby incorporated by reference.

BACKGROUND

The general purpose of the new adaptable and lockable bracket assemblies is to provide a pallet rack load stop and lock system wherein a novel bracket combines with existing beams to easily create a load stop or lock for use on all storage levels of pallet racks, including at floor-level. There are countless embodiments of the bracket assembly, several of which are herein described and others of which were described in U.S. patent application Ser. No. 13/675,346, but each can be used as either a load stop or a load lock adapter or both. The load stop system prevents damage to walls or inappropriate placement during movement of pallets onto or off of pallet racks. The load locking system prevents unwanted removal of pallets and, thus, pallet rack materials, from storage on or under a pallet rack. The general pallet rack bracket assembly is an adapter bracket made of welded steel with lock-in-place connector pins (a “clip-on” model) or bolt outlets similar to the pins (a “bolt-on” model) and existing pallet rack vertical and horizontal beams with attachment means complimentary to those of the bracket assembly.

This bracket assembly allows for universal use with a variety of pallet rack styles found in hundreds of thousands of existing warehouse facilities. The new adapter presents to manufacturers of pallet racks a low-cost option for creating a physical barrier to removal of pallets and pallet material or a barrier to over-positioning of pallets on racks, as it can be fabricated by repurposing new, leftover, and recycled partially damaged vertical pallet rack beams. Further, the new adapter is compact and easy to stock in supply houses making it readily available for customer acquisition.

The bracket assembly for pallet rack load stopping or locking is designed to connect to pallet rack vertical beams via the same mechanisms as existing pre-engineered horizontal beams, thus making the device highly adaptable and easy to use with existing materials. Since pallet racks can be engineered with different compositions and thicknesses of metal and any of several different types of connectors, the new adaptable bracket assembly can be engineered to compliment any type of pallet rack system.

Descriptions of pallet rack systems commonly reference “beam locking devices.” Though these devices sound as though they are designed or able to be used for securing pallets within pallet bays, they are, however, generally referencing devices for securing horizontal beams to vertical beams in pallet rack construction where the reference “horizontal beams” are actually the beams used to support pallets while housed within a pallet rack system. These prior art crossbeams are designed to be installed once—at the time of construction—and to bear the weight of the pallets and pallet contents. They are not designed to be removed and replaced at will and generally do not have any type of discretionary locking means, and, thus, they cannot be used as pallet rack load locks.

Another commercially available product for securing pallet contents is an “entire cover system,” which likens to a portable storage unit. These systems are expensive and impractical to implement in small or large warehouse settings, and the substantially increased surface area of such systems makes them wholly undesirable in food warehouses due to increased likelihood and difficulty in sterilizing of biological contaminations. The new bracket assembly enables a superior and simpler locking system that does not pose these challenges.

SUMMARY

The general purpose of the new bracket assembly is to provide a simple, yet versatile and adaptable, mechanism for restricting the movement of loaded pallets on and off pallet racks and within any level of pallet rack bay. In general, the bracket assembly converts a horizontal pallet rack beam into a “load stop” by securing the horizontal beam to the back of the pallet rack such that it prevents damage to walls from otherwise protruding forklifts, pallets and other devices that might be used to load and position pallets onto pallet racks. The “load lock” function of the bracket assemblies converts the load stop into a pallet removal prevention tool by enabling a horizontal beam to attached and lock to the front of a pallet rack.

DETAILED DESCRIPTION

FIGS. 1A-1F collectively illustrate one embodiment of the locking bracket assembly. FIG. 1A shows the top-side-front view of the bracket 100. The number, shape, arrangement of connectors, and locking pin hole depicted here match the number, shape, arrangement of connectors, and locking pin hole of the common upright-horizontal beam system in pallet rack and load stop manufacturing, but the number, shape, arrangement of connectors, and locking pin hole can vary depending on the type of pallet rack and purpose of the load stop. The side plates 101 are 6-inches high and can vary in length, but the commonly used lengths are 3″ and 6″. The front plate 104 is attached perpendicularly by its long edges to the side plates 101 flush with the top and bottom. 1½-inch deep “flanges” 109 attach perpendicularly to the vertical edges of the front plate. There is a pair of ⅜-inch mounting holes 105 placed through the flanges 109 for connecting to a vertical beam or for locking the bracket to a vertical beam. There is an additional pair of ⅜-inch threaded mounting holes 108 placed through the near-top-back and near-bottom-back corners of the side plates 101 for extra support for stacking two units together or bolting a horizontal beam, if needed. A locking clip pin penetrates from the back of the front plate 104 through the locking pinhole 110. There is a top plate 103 that is welded on its four sides flush to the top edges of the front 104, back 106 and side 101 plates.

This bracket assembly model can be used alone or, in an alternative embodiment, stacked with another unit to achieve desired clearance for the load lock. The front end 104 connects to the existing pallet rack vertical in the same manner as an existing pallet rack horizontal beam. Alternatively, the front end 104 can be connected (or “piggybacked”) to the back end 106 of a second bracket assembly unit 100 for added clearance. In this embodiment, bracket assembly units can clip together via the teardrop connectors and locking pin. It can be further secured by bolting the units together using the ⅜-inch holes 105—though larger sizes may be used—in the flanges 109 of one bracket assembly unit and the ⅜-inch threaded holes 108 in the side plates of a second unit.

FIG. 1B shows the top-side-back view of the stackable model 100. As described above, the number, shape, and arrangement of the connectors is variable and should be selected to compliment the pallet rack system in which the bracket assembly will be used. The back plate 106 is attached perpendicularly by its long edges to the side plates 101 flush with the top corner, bottom corner and long edge. The pallet rack horizontal beam connects to the back end of the bracket assembly. This combination of horizontal beam connected to the bracket assembly creates a load lock that can be placed at any desired height on a pallet rack vertical beam.

FIG. 1C shows the front view of the standard model 100. This view shows the front plate 104 connected perpendicularly on its edges to the flanges 109 of the side plates 101, having an inner horizontal dimension of 3⅛-inch and an outer horizontal dimension of 3⅜-inch. The male teardrop connectors 102 are spaced vertically 2 inches from the connector centers, and the minimum vertical spacing is 15/16-inch. The locking pinhole 110 is 5/16-inch in diameter and is 1/16-inch above a male connector. The male teardrop connectors and locking pin hole are set in the same configuration as necessary for connecting to an existing pallet rack vertical beam.

FIG. 1D shows the back view of the standard model 100. This view shows the back plate 106 having six female teardrop connectors 107. The female teardrop connectors 107 have minimum vertical spacing of 15/16-inch and minimum horizontal spacing of ¾-inch. The female teardrop connectors are set in the same configuration as necessary for connecting to an existing horizontal beam.

FIG. 1E shows the top view of the standard model 100. In one embodiment, the top plate 103 covers the inside of the unit, keeping it clean from dust and debris. The top plate can be a welded metal piece or a removable cap.

FIG. 1F shows the bottom view of the standard model 100. A locking pin clip 111 is attached to the back of the front plate 104. In use, the locking pin is manually inserted into the locking pinhole 110 by pressing on a clip that pushes the pin through the hole. The pin then connects to the residual space inside a female teardrop connector while the corresponding male teardrop connectors of a standard or piggybacked bracket are in place. The locking pin clip 111 locks the units together by restricting movement and, thus, preventing inadvertent lift and extraction from the connected position. The use of such clips is not restricted to teardrop connectors but, rather, is adaptable to any type of connector used in pallet rack systems (e.g., slotted, speedrack, interlake, old style teardrop, keystone, sturdibilt, T-bolt, slide-and-lock, lynx, structural, teardrop and simple bolt-and-hole).

The top of the bracket assembly can be open or solid. Having a solid top does not increase the strength because the bracket assembly is meant to be a connection bracket between a pallet rack vertical and an existing horizontal beam to create a load stop. The solid top, however, keeps the inside of the bracket assembly clean from dust and debris, which is particularly important when used on pallet racks in storage facilities that house consumable products such as produce or other food-based products.

The front flanges can be comprised of repurposed male teardrop connection plates, locking pin clip, and locking pin hole that are pre-engineered for horizontal beams. Or, the flanges can be welded onto both sides of the front plate to align the bracket assembly when connecting to a vertical beam or when piggybacking to another adapter unit. 1½″-deep flanges are depicted, but the precise depth is not critical to the function of the flanges. The back plate is derived from existing vertical pallet rack beams that are pre-engineered with female teardrop connectors. The bracket assembly can be fabricated with other materials but it is less costly to repurpose materials used to make pallet rack horizontal and vertical beams with only a few necessary modifications.

FIG. 2 shows a three-dimensional view of the bracket assembly 202 as locked to a vertical pallet rack beam 203 via a padlock 205 that extends through the flanges of the bracket and the vertical beam and is locked to a horizontal beam 201 via a padlock 204 that secures the beam through the lower side hole 206 of the bracket. In this embodiment, either side hole 206 can be used for a locking device, a bolt or left unused when the other side hole is used for locking or locking is not desired at the moment.

FIG. 3 shows the front view of the bracket assembly 302 as locked to a vertical pallet rack beam 301 via a padlock 304 that extends through the flanges of the bracket and the vertical beam and locks to a horizontal beam 303 via a padlock 305 that secures the beam through the side hole of the bracket and a locking clip 306 that is inserted from behind the abutting panel of the horizontal beam through the residual space of one of the teardrop connectors on the back panel of the bracket assembly.

FIG. 4 shows the bottom view of the bracket assembly 403 as locked to a vertical pallet rack beam 402 via a teardrop connector mechanism 406 and a padlock 404 that extends through the flanges of the bracket and the vertical beam and locks to a horizontal beam 401 via a padlock 405 that secures the beam through the side hole of the bracket and a locking clip 407 that is inserted from behind the abutting panel of the horizontal beam through the residual space of one of the teardrop connectors on the back panel of the bracket assembly.

In use, one snaps the front plate of the bracket assembly onto an existing pallet rack vertical via insertion of male connectors into the female connectors of the vertical at the desired height, then locking them in place with the locking pin just as one would attach a horizontal beam to a pallet rack vertical beam. Then, an existing horizontal beam having male connectors can be attached to the back plate of the bracket assembly by inserting the male connectors of the beam into the female connectors of the bracket assembly. A first padlock can be used to secure the bracket to the vertical beam by inserting one prong of the horseshoe mechanism through the four aligned holes of the bracket flanges and the vertical beam and then engaging the locking mechanism. A second padlock can be used to secure the bracket to a horizontal beam by latching through the aligned side panel hole of the bracket and corresponding hole in the abutting panel of the horizontal beam. The result is a height-adjustable, locked barrier to pallet removal.

As to further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of this invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention, the use of which results in a pallet rack locking system.

Although the description presented heretofore contains specificities for the benefit of illustration, these should not be construed as limiting the scope of the embodiments but rather as illustrative examples of some of the several embodiments. For example, bracket assemblies may primarily be made from 14-gauge steel since most existing pre-engineered standard duty pallet rack uprights are made of 14-gauge steel. There exist, however, other pre-engineered heavy duty and light duty pallet rack uprights and horizontal beams that are made of a thicker or lighter gauge depending on the required support. Bracket assembly load stop adapters can and should be made from steel of a gauge thickness and connection type complimentary to that used in the uprights and horizontal beams with which the bracket assembly will be utilized. Further, the locking mechanism could employ a means other than a padlock, such as a zip tie, depending on the specific use of the load lock. Thus, the scope of the embodiments should be determined by the appended claims and their legal equivalents rather than by the examples provided.

FIG. 5 shows the locking bracket assembly in use on a pallet rack. In one embodiment, two bracket assemblies 500 are shown as attached to two parallel vertical beams 501. Each bracket assembly is locked to a vertical beam via a padlock 502 that extends through the holes in the flanges of the bracket assembly and the holes in the sides of the vertical beam. Each bracket assembly is also locked to a horizontal beam 503 via a padlock 504 that secures the beam through a side hole of the bracket assembly. The locked horizontal beam 503 prevents the removal of loaded pallets 505.

FIGS. 6A-6J depict the bracket assembly, with and without flanges, having a ⅛-inch-wide vertical front-end gap. The gap allows for subtle but often critical adjustment of the width of the male teardrop connectors, as the width of female teardrop connectors on vertical pallet rack beams can vary slightly among manufacturers.

FIG. 6A shows a top view of an assembled 3-inch bracket assembly 600 with right and left 3-pin front end plates 601 with flanges 603 spaced ⅛-inch apart to allow for the adjustment gap 604 and welded to the back of a 6-inch deep vertical column 605.

FIG. 6B shows a top view of an assembled 3-inch bracket assembly 606 without flanges and having a gap 604 between the front end plates 601.

FIG. 6C shows the right and left front end plates 601 of the bracket assembly with flanges having three male teardrop connector pins 607 on each side.

FIG. 6D shows the right and left end plates 601 of the bracket assembly without flanges having three male teardrop connector pins 607 on each side. Each end plate is extended by a two-inch metal piece 608 welded to and in line with the end plates. Each extension piece 608 contains a central bolt hole 609, through which a bolt can further secure the bracket assembly to a pallet rack vertical beam.

FIG. 6E shows a side view of a 3-inch bracket assembly 600 with flanges 603 welded to the back of a 6-inch deep vertical column 605.

FIG. 6F shows a side view of a 3-inch bracket assembly 606 without flanges and having an extension piece 608 extending from the bottom of the end plates.

FIG. 6G shows the top view of a clip-on bracket assembly 605 with flanges 603 attached by the front to a pallet rack vertical beam 610 via six teardrop connectors 612 and attached by the back to a horizontal pallet rack beam 611 via three teardrop connectors 614. In this embodiment, both the front and back teardrop connections 612, 614 are secured by locking pins 602, each of which fits into the empty space present in the female teardrop connectors when the male teardrop connectors are in place.

FIG. 6H shows the top view of a clip-on bracket assembly 605 as depicted in FIG. 6G but without flanges.

FIG. 6I shows the side view of a clip-on bracket assembly 605 with flanges 603 attached to an vertical pallet rack beam 610 via teardrop connectors 612 and further secured via bolts 616 that extend through opposing bolt holes in the flanges and corresponding holes in the sides of the vertical beam. The bracket assembly 605 is attached by the back plate to a horizontal pallet rack beam 611 via teardrop connectors 614.

FIG. 6J shows the side view of a clip-on bracket assembly 605 as depicted in FIG. 6I but without flanges and having a two-inch enhancement 618 of the front plate that extends below the main body of the bracket assembly and has a centrally place hole through which a bolt 617 can be used to further secure the bracket to the vertical beam.

FIGS. 7A-7E depicts a U-shaped embodiment of the bracket assembly. This U-shaped bracket assembly can be mounted to an inner side of a vertical pallet rack beam as opposed to the outer side and, thus, is better suited for use on closed-back pallet rack vertical beams. Whether mounted to an outer side or an inner side of a vertical beam, this U-shaped embodiment is adjustable, allowing for three to nine inches of desired clearance.

In terms of production value, this model does not require welding and is less costly to produce than most other embodiments. Some pallet racks do not have an open back so the front bolt on will not work for closed back pallet rack vertical beams.

FIG. 7A shows the top-front-side view 700 and the top-back-side view 704 of one embodiment of an adjustable U-shaped bracket assembly having bilateral flanges 702 attached to two side plates 701.

FIGS. 8A-8B collectively illustrate another embodiment wherein the bracket assembly can be attached to the vertical pallet rack beam via bolts through bolt holes in the end plate of the bracket assembly and into the female teardrop connectors of the vertical beam instead of male teardrop connectors on the end plate.

FIG. 8A shows the top-side-front view 800 of the bolt-on model. In one embodiment, the front plate 801 is embellished with six holes 802 at least ⅜-inch in diameter, through which bolts can be inserted. Use of only one of the top hole and one bottom hole is necessary for secure bolting. The front side can connect to a pallet rack vertical beam or to the back of either another bolt-on or a clip-on bracket assembly for extended length.

FIG. 8B shows the top-side-back view 803 of the bolt-on model. In one embodiment, the back plate 804 contains six female teardrop connectors 805. The number, shape, and arrangement of the connectors is variable and should be selected to compliment the pallet rack system in which the bracket assembly will be used. The pallet rack horizontal beam connects to the back end of the bracket assembly.

FIGS. 9A-9E depict a three-piece adjustable model of the bracket assembly wherein mounting bolts attach flanges to the bracket assembly side plates through slits, allowing for adjustment in clearance from 6 to 9 inches.

Visible are the four bolts 903 that extend through the side slits 905 of the flanges and bracket body, as well as the two mounting bolt holes 906 positioned toward the front of each flange and the two mounting bolt holes 907 positioned toward the back of each side plate of the bracket body.

FIG. 9C shows the top-front-side view 908 of the three-piece adjustable bracket assembly.

FIG. 9D shows the top-back-side view 909 of the three-piece adjustable bracket assembly. The back plate 910 can be seen clearly, having six female teardrop connectors 911 for attaching the bracket assembly to a horizontal pallet rack beam.

FIG. 9E shows the top view of a six-inch U-shaped adjustable bracket assembly attached by the front end to an upright pallet rack beam 912 via a bolt 913 extending through the mounting bolt holes of the bilateral bracket flanges and also through the corresponding holes of the upright beam.
